Spring training is heating up in Peoria, Ariz., and the Mariners -- as of Monday -- are already 3-1 in Cactus League play. The sun has been shining and baseball is just around the corner, so we thought it was time to get to know this year's Mariners a bit better.

Click through the gallery to learn some fun facts about the 61 Mariners who are at spring training -- the 40 guys on the MLB roster and the 21 minor-leaguers who were invited to show their stuff.

Fun fact: Spent this past offseason ''learning how to run.'' His slow gait has been the subject of some ridicule since he joined the M's as part of 2012's preseason Michael Pineda trade to the Yankees.

Fun fact: Known as ''The Beast,'' he's on his second stint in the Mariners organization after being traded to the Nationals (for Ryan Langerhans) in 2009 and getting traded back this past January from Oakland (for John Jaso).

Fun fact: Nicknamed ''The Boog'' by his dad, after major-leaguer Boog Powell. Likes to goof around and do impressions -- including a great Robert De Niro knockoff. Also co-stars with a buffalo in a 2013 Mariners commercial.

Fun fact: His brothers, Justin and Corey, are also baseball players. The Dodgers drafted Corey in 2012 with the 17th-overall pick, and Justin is a junior infielder at the University of North Carolina Charlotte.

Fun fact: Got an invitation to M's spring training with just a year of minor-league baseball under his belt. Led the High-A High Desert Mavericks in 2012 in saves (15) and only allowed two runs over his final 28 games.

Fun fact: Grew up in Schenectady, N.Y., and hit a key home run at Yankee Stadium in front of 20 friends and family members -- including his mom -- on Mothers Day 2012. Also is the fifth guy in his family named Casper.

Fun fact: Is nicknamed ''The Bartender'' because he became a bartender in Tuscon, Ariz., after giving up on a minor-league baseball career with the Brewers organization. But in 2009 he quit smoking and, after marrying his wife Cassie, decided to get back into baseball and got signed in 2010 by the Mariners.

Fun fact: The Mariners' first-round pick (second overall) in 2012, he comes from a baseball family -- his dad, Greg, is a scout for the Reds and his mother, Paola, was a catcher on the Italian national softball team.
